About this tag
The b2b guests tag covers guidance for managing external collaborators whose SharePoint and OneDrive access is moving to Microsoft Entra B2B. Current coverage focuses on the July 2026 transition and the practical work administrators should complete before access becomes urgent: exporting SharePoint external-sharing reports, reviewing User E-mail values, matching addresses to existing Entra guest identities, inviting priority collaborators who are missing, and testing the precise site, file, folder, or OneDrive item each person needs.
